Phenotype: shortened QRS complex duration

Definition decrease in the length of time of the largest-amplitude portion of the ECG, caused by currents generated when the ventricles depolarize prior to their contraction; prolongation of the QRS complex duration reflects slowed conduction in the heart

Synonyms
  • narrow QRS complex
  • narrow QRS complex
  • shortened QRS duration
